ILLUMINATED SIGN- Specification of Letters Patent,

Patented Nov. 21, 1905.

Application filed September 16, 1904. serial No. 224,684.

To all whom it may concern.-

Be it known that we, ELIAs L. ELLIOTT, a citizen of the United States,residing at Lakewood, in the county of (Juyahoga and State of Ohio, andEUGENE LUCIEN, (Marquis Oarlet de la Roziere,) a citizen of the FrenchRepublic, residing at Paris, in the Republic of France, have invented acertain new and use ful Improvement in Illuminated Signs, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings.

The object of this invention is to provide in a very simple form anilluminated sign attractive in appearance and one which shall require aminimum of electric current for its lighting. In accomplishing thisweform a sign of reflecting-letters placed in rows, each row beingforward of the one inside thereof, and the surface of the forward rowsbeing of increasing inclination toward the axis, whereby the rows as awhole form an interrupted concave mirror. At the focus of this mirror weplace an electric lamp Whose rays are reflected by the letters composingthe sign. Our invention comprises such an illuminated sign, and theinvention is more fully hereinafter described, and its essentialcharacteristics are set out in the claims.

In the drawings, Figure 1. is a front view of the sign, and Fig. 2 is avertical section therethrough.

Referring to the parts by letters, A represents any suitable standard orfixture carrying a supporting-surface B, which is preferably of the formof a parabola in section. This surface may be conveniently made ofwire-netting. Secured to the support B are the letters O, whichconstitute the sign. These letters are made of reflecting material andmay be placed in concentric rows around the axisof the parabola. Asingle incandescent electric lamp D is placed at the focus of theparabola, and its rays passing to the letters O are re- An opaqueflected forward in parallel lines.

shield E is placed in front of the lamp, and the surface of the supportBbetween and around the letters is painted black to prevent thereflection from any surface but the letters. By this means theilluminated letters will be the only part of the device visible at nightfrom a little distance away, and a very pleasing effect is produced. Therear side of the shield is preferably made reflecting to return theforward rays from the lamp to the reflectingletters.

We claim- 1. In an illuminated sign, a support carrying the lettersforming the sign, the surfaces of the letters being approximatelyparabolic, a light for illuminatingthe letters disposed at the focus ofthe parabolic surfaces in such manner as to illuminate the letters andcause the rays of light reflected therefrom to be thrown forward.

2. In an illuminated sign, a support carrying letters, said lettersbeing concaved so as to present an approximately parabolic surface, alight for illuminating the sign placed at approximately the focus of theparabolic surfaces of the letters in such manner as to cause the rays oflight reflected from the letters to travel forward and a shield placedin front of the light in order to prevent itfrom being normally visible.

3. In an illuminated sign, a concave support carrying letters in suchmanner as to present an approximately parabolic surface, and a light forilluminating the sign placed substantially at the focus of the paraboliccurve, all arranged in such manner as to cause the reflected rays totravel forward in approximately parallel lines.

In testimony whereof wehereunto afiix our signatures in the presence oftwo witnesses.
